This is a linden, Tilia platiphyllos. It was collected in Germany by Wolfgang Kaeflein in 2001. David acquired it and started to work on ti. I inherited it in a trade this summer. Normally I work on such material from March to May. But we are having the warmest November ever with spring-like temperatures. And I can work outside. So I gabe it a go because linden are some of the most hardy deciduous trees. A tree which was wired like this one normally must have good winter protection. But a linden can stand it with some protection, I hope. With more than 600 bonsai there just is no room for winter storage anymore.
